Abstract

L'invention concerne un procédé et un appareil de broyage à sec d'une matière granulaire dans un tube broyeur 1 comportant un compartiment final 2 et un ou plusieurs compartiments antérieurs 3 contenant des corps de broyage. Après son passage dans le ou les compartiments 3, la matière est déchargée par des ouvertures 6 du tube broyeur 1 et est répartie en des fractions finement divisée et grossière dans un séparateur 9. La fraction grossière est ramenée dans le ou les compartiments antérieurs 3 et la fraction finement divisée est introduite dans le compartiment final 2. Les corps de broyage qui passent par dessus un barrage annulaire 12 avec la matière broyée sont séparés de cette dernière par un diaphragme de tamisage 13 et ramenés dans le compartiment final 2. Application au broyage à sec d'une matière granulaire telle que le ciment.The invention relates to a method and apparatus for dry grinding a granular material in a grinding tube 1 having a final compartment 2 and one or more front compartments 3 containing grinding bodies. After passing through the compartment (s) 3, the material is discharged through openings 6 of the grinding tube 1 and is distributed into finely divided and coarse fractions in a separator 9. The coarse fraction is returned to the front compartment (s) 3 and the finely divided fraction is introduced into the final compartment 2. The grinding bodies which pass over an annular barrier 12 with the ground material are separated from the latter by a sieving diaphragm 13 and brought back to the final compartment 2. Application to grinding dry of a granular material such as cement.
